Hybrid tea rose plant named ‘JACwypin’

ABSTRACT

Hybrid tea rose plant having vigorous, well branched, upright growth; dark green, glossy foliage; distinctive bicolor flowers; strong, fruity flower fragrance; high centered flower form; and ease of propagation on its own roots.

Genus and species: Rosa hybrida.

Variety denomination: ‘JACwypin’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a hybrid tea rose plant named ‘JACwypin’ which was originated by me by crossing an unnamed, unpatented pink hybrid tea seedling, (Silver Jubilee×Ingrid Bergman) with the variety ‘JACsee’ (U.S. Plant Pat. No. 11,138).

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety having the robust growth, high centered flower form and disease resistance of the female parent combined with the fragrance of the male parent.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

-   -   1. Vigorous, well branched, upright growth.     -   2. Dark green, glossy foliage.     -   3. Distinctive bicolor flowers.     -   4. Strong, fruity flower fragrance.     -   5. High centered flower form.     -   6. Ease of propagation on its own roots.

Asexual reproduction of this new variety by cuttings, as performed at Wasco and Somis, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

‘JACwypin’ differs from the pink female parent in flower color and possessing fragrance and differs from the male parent in flower color.

Comparison with Similar Variety

‘JACwypin’ compares to hybrid tea roses with bicolored flowers like Love (‘JACtwin’, U.S. Plant Pat. No. 4,437), Rosie O'Donnell (‘WEKwinwin’, U.S. Plant Pat. No. 11,382) but differs from all of them in flower color and in fragrance, which others lack.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart© 2001, except where ordinary dictionary significance of color is indicated.
